This document discusses databases in bioinformatics. It begins by noting the rapid increase in biological data from sources like gene sequences, protein sequences, structural data, and gene expression data. It then defines biological databases as structured, searchable collections of data that are periodically updated and cross-referenced. The major purposes of databases are to make biological data available, systematize the data, and allow analysis of computed biological data. The document provides a brief history of biological databases and sequencing efforts. It also classifies biological databases based on data type, maintenance status, data access, data sources, database design, and organism. Specific databases discussed include DDBJ, EMBL, GenBank, Swiss-Prot, and NCB
The Protein Data Bank (PDB) is a database for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids. This presentation deals with what, why, how, where and who of PDB. In this presentation we have also included briefing about various file formats available in PDB with emphasis on PDB file format

BIOLOGICAL DATABASES :
A biological database is a large, organized body of persistent data, usually associated with computerized software designed to update, query, and retrieve components of the data stored within the system.
The chief objective of the development of a database is to organize data in a set of structured records to enable easy retrieval of information.
Example. A few popular databases are GenBank from NCBI (National Center for Biotechnology Information), SwissProt from the Swiss Institute of Bioinformatics and PIR from the Protein Information Resource.
IMPORTANCE OF DATABASES :
1. Databases act as a store house of information.
2. Databases are used to store and organize data in such a way that information can be retrieved easily via a variety of search criteria.
3. It allows knowledge discovery, which refers to the identification of connections between pieces of information that were not known when the information was first entered. This facilitates the discovery of new biological insights from raw data.
4. Secondary databases have become the molecular biologist’s reference library over the past decade or so, providing a wealth of information on just about any gene or gene product that has been investigated by the research community.
5. It helps to solve cases where many users want to access the same entries of data.
6. Allows the indexing of data.
7. It helps to remove redundancy of data.
TYPES OF BIOLOGICAL DATABASES:
Biological databases are classified on
1. Based on content of biological data
2. Based on the nature of data.
1. BASED ON CONTENT OF BIOLOGICAL DATA :
Based on their contents, biological databases can be roughly divided into two categories:
1. Primary databases
2. Secondary databases
Bioinformatics is the application of Information technology to store, organize and analyze the vast amount of biological data which is available in the form of sequences and structures of proteins and nucleic acids. The biological information of nucleic acids is available as sequences while the data of proteins is available as sequences and structures.
A biological database is a collection of data that is organized so that its contents can easily be accessed, managed, and updated. The activity of preparing a database can be divided in to:
Collection of data in a form which can be easily accessed
Making it available to a multi-user system (always available for the user)

What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Students, digital devices and success - Andreas Schleicher - 27 May 2024..pptxEduSkills OECD
Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. Introduction
Fast increase in biological information
Biological science has now turned into a
data rich science
Gene sequences
Amino acid sequences in proteins
Motifs and domains in proteins
Structural data from XRD & NMR
Metabolic pathways
Protein-protein interactions
Gene expression data DNA microarrays
3. Biological databases
Biological database is a collection of
data which is structured, searchable,
updated periodically and also cross-
referenced.
Some databases are multi functional
Major purposes of databases is as
follows:Availability of
biological data
Systemization
of data
Analysis of
computed
biological data
4. History

was sequenced
51 amino acids
Atlas of protein sequences and structures in
1965 by Margaret Day Hoff et al was a
printed book.
Became base for PIR protein information
resource
First nucleotide sequence: yeast tRNA
